I have moved this thread to the VSE community.
What EXACTLY were the 100 adware issues that Spybot found? If they were mainly cookies, then I've not found the McAfee Antispyware module to hit on them much.. Besides, cookies aren't really much of a risk..
On the other hand, it sounds like you may have installed McAfee on an infected machine which had no previous protection.. If that's the case, then it's possible the malware disabled McAfee's ability to work correctly.. General instructions for installing any such software is to clean out the machine first, using tools of your choice, then install McAfee.
As to other tools for spyware/adware, there are other tools available but since this is a McAfee forum, you'll need to do your own research for such things.. Make sure you check the various tests/reviews for all the products available.
Hope this helps.
Just to add -
VirusScan Enterprise 8.x will not detect any cookies, until you have added the corresponding AntiSpyware module for your product.
Without the module VSE can still detect some potentially unwanted programs, but that does not include cookies.
What is the antispy modul for 8.7i then? I will look on our portal page for it.
